IMPROVEMENT IN APPARATUS FOR--E-M'PTVING PRIVVVIAIUL'T Specification forming part of Letters PatcntNo. 96,*35, dated'November 2, 1869.

To all whom it may concern:

Be it known that I, J. G. BERGER, of Nuremberg, in the Kingdom of Bavaria, have invented a new and useful Machine for Cleaning Privy-Vaults and Cisterns Containing Putrid and Noxious Matter; and I do hereby declare that the following is a full, clear, and exact description of the same, sucient to enable others skilled in the art to which my invention appertains to fully understand and use the same, reference being had to the accompanying drawings, which are made part of this specification, and in which- Figure l represents a side view of the machine mounted on a vehicle, in connection with a port- 'able air-tight reservoir or receiver for containing the matters removed from the vaults; also, a gas-burning stove consuming` the gases arising from said matters. Fig. 2 is a top view thereof, partly in section.. Fig. 3 is an end View, partly broken away to show the interior of the cylinder and suction-chamber. Fig. 4 is a detailed view of certain parts of the machine.

The object of this invention is to facilitate the discharge from privy-vaults and other reservoirs of putrid and noxious matters, and delivering the same into a suitable receiver mounted on any vehicle, so as to be transported to any desired place; and it consists in certain improvements in the working apparatus of such machines, hereinafter more fully described'.

In the drawings, A represents the bedframe, with uprights a a a a', on which the entire machine rests, this frame being secured to the wagon W. e

The axis H of the ily-wheels G is journaled on the -uprights a a. The wheels are provided with handles. On one side of this axis is secured a small toothed wheel, M, which meshes into a larger one, L, which is journaled on the crank-axle L. This axle also c arries the fork or guide-rod F, and at the outer end the eccentric X. This is the gearing mechanism which shall give the requisite motion to the piston D and valve N. The piston D is secured in a suitable manner to the rod D. This rod has secured to it the guide-plate, commonly called cross-head, D", which slides freelylto and fro on the fork Iis connected with, and receives F. The valve N of the receiving-chamber C its motion from, the eccentric X.

`The end of the rod K which comes in contact with the periphery of the eccentric is of such shape as to admit the insertion of a friction-roller, m, between it. A similar roller is placed on the opposite side, and a block, of like shape as the end of the rod K, is held in contact therewith by means of metallic bands extending alongside the eccentric, and screwed or fastened in any suitable manner to the end of rod K and the block x. By this arrangement I greatly lessen the friction which would otherwise exist between these two parts.

' The cylinder B is made of cast-iron, and

formed with the necessary inlet-ports, which communicate with the receiving or suction chamber C. The outlet-pipe P is secured in any suitable way, so as to convey the putrid and noxious matters tothe receiver Z.

By these machines it frequently happens that solid matters are drawn into the receiving-chamber C, and should they be allowed to enter into the cylinder they would prove very fatalwell known to those acquainted therewith. It has been my aim to obviate this` difficulty in a very effective manner, viz: I secure to the face of the cylinder, or that part over which the valve N slides to and fro, and marked a.X bx c", with a steel plate, O, secured thereto by means of set-screws f. Thus the plate, when worn out, broke, or otherwise injured, can be readily removed, and a new one substituted. This plate-that is, the parts a* x bX X cX X thereof-forms an acute angle, as plainly seen in Fig. 4. The office of this-plate is to cut the paper or any other like solid substance before entering the cylinder. By this arrangementl dispense with the use of addi tional knives hitherto employed for like purpose in these machines. A similar plate, e', is affixed to the face of the valve N.

To have ready accessto the interior of the receiving-chamber C and cylinder B, I have provided the former with a detachable lid, E, which is held hermetically to its place by the clamp e e and screw T. The ends ofthe clamp are formed in hooks, so as to gripe the anges of the casting constituting the chamber C.

. The operation of' the machine is simple and plain, Iand it', is,'theref'ore, thought unnecessary to ,dwell upon it.

Having thus described my invention, what` l claim as new therein, and desire to secure by Letters Patent., is

1. The combination and arrangement of the driving-shaft H, with its gear-wbeel M, crankshaft L', with its wheel L and eccentric X, endvalve-rod K, provided with the yoke and friction-rollers :c as herein described.

2. The sharp inclined-edged steel plate O,

secured to the cylinder at the inlet-ports, in combination with a simiierlyfedged plate, e',

upon the face of Jche valve, whereby the seid plates are madeALo operate like shearblades, to cut or seperate any substances that may Y tend to choke the ports, substantially es described J. G. BERGER.
